HRR21VKA - flywheel brake shot

Are there any instructions anywhere on how to replace the brake on the flywheel? When I let off the lever to stop the mower, she grinds very loudly. I can't find instructions anywhere. I have done a search on this forum and can not locate it.

thanks for any help you all can give me.

Regards, Wally "FishnFed"

Edit - should be HRR216vka
